JAMESROBERT PEIFR, F SHEPPTON, PENNSYLVANIA.

FAN-BLOWER.

Be it known that I, JAMns ROBERT PnrrER, a citizen of ythe UnitedStates,` residing at Sheppton, in the county of Schuylkill and State of'.Pennisi lvania have invented certain new and useful Improvements inFan- Blowers; and I `do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains` to make and usethesame.

My invention relates to new andy useful improvements in fan blowers andmy object is to provide a fan and means to operate the same and assemblethe casings around the parts whereby the structure will occupy but aminimum amount of space. l

A further object is to provide avent for the admission of air into thefan housing.

A further object is to provide means for attaching the blower toupartsof a stove. f

A further objQQLiS..toiprovide means for ""conve'ying'the air from thefan housing to a point below the grate in the fire box. And a furtherobject is to\ provide kmeans for covering the openings inthe airconveying means whereby ashes and the like Awill beexeluded therefrom. fM l vOther objects and advantages will be hereinafter set forth and moreparticularly pointed out in the accompanying specification.

ln the accompanying drawings which` are made a part of this application,Figure 1 is a sectional 'view through heatingvstove, showing my improvedfan mechanisml attached thereto. Fig. 2 is an end elevation of the fanmechanism removed from theV stove. Fig. 3 is a plan view 'of the pipeemployed for conveying the air to a, point below the grate, and Fig. 4is an enlarged transverse sectional View thereof.

Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, l indicates a stovewhich may be constructed in the usual or any preferred manner employedfor heating or cooking purposes, 2

indicates the fire box and 3 the grate therein.

Secured at any suitable point to the wall kof the stove and preferablyin the rear thereof ismy improved form of fan construction comprlsing ahousing 4, the outer wall 5 of which is removably secured to theremaining portion of the housin said wall being held in position byintro ucing bolts y Appiiieatioptied December i1, 1915. serial No.66,392.

l Specication of Letters Patent. Pntnted June 13, 1916,

i orricn 6 through the inner wall and threading the ends thereof intofillets 7 on the inner face of the outer wall. Rotatably mounted inbearings 8 'at the axial center of the housing is a shaft 9 to which isattached a fan 10, said shaft extending through and beyond the outerwall 5 and has a pinion l1 fixed thereon with which meshes a drivinggear 12, said driving gear being likewise mounted upon a shaft 13 oneend of which finds4 a bearing in the outer` wall 5, while the oppositeend projects through the wall of an auxiliarycasing 14, the extremeouter end of theshaft 13 having a crank 15 attached thereto by means ofwhich rotating motion is imparted to the driving gear.

The auxiliary casing 14 comprises a circularplate 16, the peripheraledge of which is provided with the iange 17 which pro- .jects at rightangles to the circular plate,

the lower portion of said flange resting against the face of the outerwall 5, while the upper portion thereof projects above the housing 4andtelescopes with a iange 18 of a semicircular plate 19, saidsemicircular plate havinga flange 20 at its inner edge which rests uponthe edge wall of the hous-y ing 4 and is secured thereto in anypreferred manner, said housing and casing forming a complete coveringfor the fan and gears and by arranging the gears in the manner shown,the fan construction may be assembled in compact formation. l

In'order to admit air into the housing 4, an opening 21 is formedthrough the outer wall' 5 which opening is substantially crescent shapeand is `positioned immediately below the edge of the auxiliary casing 14solthat the air will be admitted to the fan at a point yadjacent itsaxial center. The housing 4 is provided with an integral nozzle 22 whichis preferably positioned below the housing and has connected to itsVlower'end a pipe 23, the coupling 24 employed for securing the pipe tothe nozzle' being so constructed that said pipe may swivel in thecoupling and be directed at variousl angles as occasion may require.

The pipe 23 is preferably directed at right angles to the vertical trendof the housing and is adapted to be introduced into the stove at' apoint below the re grate, the upper portion of said pipe having aplurality of ports 25 therethrough through which the air escapes and byplacing said ports in the upper face of the pipe the blast` of air willbe directed through the grate and into di-V rect'contact With the kfuelresting thereon.

ln order to prevent ashes, or the like, from Venteringthe'ports 25, asthe ash is shaken `from the grate 3, a shield 26 is positioned overtheface of the pipe 23, said shieldbeing inthe arc of a circle andfitting the outer periphery of the pipe, transverse slots Q7 beingYformed in the shield adjacent its ends throughV which project studs 28carried by the'pipe '2.3 and by means of which the rotating movement ofthe shield upon the pipe is limited. The movement of tle shieldrisregulated by means of a lever 29 .which is preferably rfformed integralWith Y one end of the shieldand projects exteriorly of the Wall of thestove sothat the lever may be readily grasped tofswing the shield to aposition toy cover or uncover` the ports', the

weight of the shield'serving to hold the same Y against casualrotation.`

The prime object of Vmy invention is to provide a blast of air toincreasethe heating capacity-of the fuelV Within the fire box` so thatthe 'temperature Within the ,stove may be greatly increased in a veryshort period oftimeV and the device is further applicable forcausing thefuel to readily ignite When theviire is first started andby introducingthe'pip into the ash receiving comlll'illllll ofthe stove immediatelybelowrftli grate on Whichthe fuel is resting-these results'vvill bereadily accomplished. l Y

When Va blastof airis to be directed through theY grate and'intocontactWith the w fuel, thelever 29 is'depressed, thereby rotating the shield26around the pipe 23 the full l length of the slots27 and thusuncovering the'pcrts ,25.A The crank 15K is then rotated Whichwilloperate the fanV 10V and force the Y air through the pipe 28and ports25, andin view of the fact that the opening "21 is placed adjacent theaxial center of the fa .Copies o'f'this patent may be obtained'fo ar,suction `Will be caused within thehousing i when the fany isl rotatedand a constant supply of air drawn into the housing.'

As soon as the temperature Within the stove has been raised fto theproper degree Y byineans of the'forced draft, the' shield 26V is rotatedin the jopposite direction through the medium of the lever29 and theports 25 covered over so that the ashes falling from the iirebox Will beprevented from entering the ports 25 and clogging the interior oftheVpipe 23.

Having thus fully described my invention What I claim as new and desireto secure by LettersPatent of the'United States, is

l. Yln afanblotver for stoves, furnaces andV the like, the combinationWith aV housing having a dischargenozzle, a fan'mounted in said housing,and means to operate said fan to direct a blastV of air throughthenozzle,

of'a pipesivivelly' connected, to said nozzle for adjusting the angularrelation of said pipe relative to saidnozzle, said pipe havj ing aplurality of Vports therein, a curved solidV shield embracing the uppersurface of said pipe and having transverse slots therein adjacent itsends, studs extending through said slots and into theV pipe 'forlimiting the adjustment of said shield, andra VleverV con'- nectedtosaidshield by means of Which lthe shield may be vmovedftfo position to coveror uncover saidfports.A

2. Ablower for stoves, furnaces and the like,comprising a housing havinga removablefouter iva'll, said router Wall having an air receivingopening therethrough, ashaft rotatablyfmounted in saidv housing, a fancarried by said shaft, a pinion fixed to said shaft, a` driving gearmeshing with said `pinion, an auxiliary casing surrounding saiddrivinggearand pinion, said casing comprising a circular plate having anangularly extending yfiange at Vthe peripheral edge thereof, aseinicircular plate having a flange thereon adapted to telescope'vvith;the flange of the first plate,y means to connect said plates together`and t'o said housing, a crank for operating said driving gear forrevolving said fan, and means to convey'the blast y of vcreateil by saidfan to points beneath agrate.
